AudioChorusFilter 音频合声滤波器

The Audio Chorus Filter takes an Audio Clip and processes it creating a chorus effect.

音频合声滤波器采用一个音频剪辑并处理它，创建一个合声效果。

The chorus effect modulates the original sound by a sinusoid low frequency oscillator (LFO). The output sounds like there are multiple sources emitting the same sound with slight variations - resembling a choir.
